Hi, Codeforces!

This is not an ordinary post from me. This is not an announcement of new features or a championship, but I'm no less enthusiastic.

I am glad to inform you that from January 29 to February 16, 2018 I will be giving the course "Advanced Algorithms and Data Structures" in Harbour.Space University (Barcelona, Spain). The course will be in English. The students of this course will not only be students of Harbour.Space, but is open to all! Who wants to join?

This course isn't just for Harbour.Space students, it is also open to Codeforces participants, who will be offered a special price, 1000 EUR. The cost does not include travel or accommodation.

In my plans there is a detailed story about some algorithms and data structures, a lot of practical exercises and emphasis not only on the correctness, but also the beauty and structure of the code. My goal is to make useful and interesting classes for both those who want to understand the fundamental CS, and for those interested in programming competitions. And of course, we will have the opportunity to meet and talk. I'm happy to share stories about the history of Codeforces and development plans.

The course will consist of three weeks of training, 5 training days in each week. The program includes daily lectures and practical exercises. It will not be boring for sure!

Here is the expected course outline:

And how many of those 1000 euros per participant go to you?

I'm up for paying, recording the lectures and reselling them at 50 euros per whole course. I'd pay off my costs and send the profits to you directly. (jk ofc)

    By the same argument, I can buy one of yours and resell it for 1 euro. So I think that the recordings should be free.

      Whoever wants it for free will find a way to get it for free. My way makes the course affordable and rewards author of the course with sth like donations from people who want to pay for it (don't tell me there wouldn't be anyone, CF has plenty of supporters) instead of helping moneylenders.

        I don't know their business model, but I was expecting something like coursera/edx (pay only if you want the certificate). The goal of universities is the creation and distribution of knowledge, so I don't find any reason to not let the recordings for free, for example, in Brazil there is an annual international training camp and all the material (lectures/contest problems) are available for free.

Am I the only one who thinks that this course is ridiculously expensive? I know that the course will be professionally prepared, but really? 1000€?! If you add travel, accomodation and food (for 3 weeks) that's pretty expensive. I know that some people and/or universities can afford this, but on the other hand, I am organizing camps in Poland that cost at most 100€/week with accomodation, travel (within the country), food and several lecturers.

    I assume you don't pay much money for teachers (preparing the lectures also takes time) and the university gives classrooms for free?

    Still, I also think 1000€ is expensive for this course. In my university in Finland, a visiting lecturer gets about 100€/h and a classroom costs about 50€/h. So organizing this course would cost about 150*3*15=6750€. So you would only need seven participants to cover all costs.

      We organize camps either in the university classrooms (and we don't pay for them, or in hotels with conference rooms (we pay for them).

      And yes, we don't pay 100€/hour to lecturers and tutors, but we have really healthy environment here in Poland. Most of our participants later help organize those camps and they are really pationate about it. We are organizing such events not to earn money, but to help others.

      We are still paying them for their time.

        Yeah, we also have a "healthy environment" in Finland — because we don't have money to pay appropriate salary for competitive programming training. 100€/h is what a lecturer would get in an "official" university course, this doesn't apply to our random training camps.

      You expect the course to be 3 hours per day? 150*3*5*8 = 18,000

    Maybe for Poland it's expensive. In the UK a 1 week training course is typically £2,000 so 3 weeks would be £6,000

      I see your point. But I believe that science should never be exclusive the privileged. Many great institutions offer their recorded courses for free, MIT open courseware for example. I have watched lots of recorded complete courses taught in universities everywhere.

        Joker: "If you're good at something, never do it for free."

        Bill Gates, net worth ~90 B dollars

        Mark Zuckerberg, net worth ~71 B dollars

        Linus Torvalds, net worth ~150 M dollars

        To give you a perspective to their net worth difference:

        90,000,000,000$

        71,000,000,000$

        .....150,000,000$

        You see the difference? No matter how good is your product, if you don't make a value to the customer, you will earn no shit. Harder part is to make people to buy your product, than to make it.

        Mike wants to share some knowledge with you, why would he share it for free? The other thing is wheter his strategy to earn something from it (with this approach and price) is good or not.

          I'd hardly call being worth 150m dollars "earning no shit". Besides I really don't see the point in making as much money as possible at all times. To be frank I don't really understand why someone would want to earn much more than the cost of living, but people can do whatever they want.

          Anyway I hardly doubt any of this is Mike being greedy. I suspect most of the "extra" money is snatched by Harbour.space & co. I doubt Mike has any real control over the pricing of these things.

            As you said, different people have different view of how much is enough money.

            "Mike is being greedy" is your opinion, because for you and many other people (including me) 1000$ for something like this is a lot. But there are other people who would think it's a fair enough. Different value of product for different people. Everything has some value, it is just how you make it to the public.

                I understood that you think he is not greedy because little of that money will go to him and he would like to share his knowledge for free. But if course was 10K EUR, you would say: "This is too much, I think he is little greedy."

                Point is that you think someone is greedy if he evaluate product/services through money more than you. Example: "Hey this is too expensive, he just wants to earn some extra money, he is greedy." Greedy is relative. And YES he needs to ask for money for his services.

                But still I would like this to be online/free as well. However, this would be a good way to upgrade Codeforces servers.

I would like to know how well the lectures are prepared. Would you make some of them available for free? Also, this is a popular marketing strategy. I'm not going to register even if they are worth the 1000 EUR (because I don't have the money lol). However, I guess, there will be other people who would :3

oh, wow, that looks like the course that would fill in all the gaps for me! content at a reasonable price that doesn't offend. the next thing i'll do is go directly to my manager and tell him all about going away for three weeks, and i'm sure he won't care.

You might see me there in Barcelona!
